IMHO, it's only a matter of time - and not too far into the future, I think - that they'll be interviewing potential recruits with only turbo time. Again IMHO, I don't think this will be a bad thing. I'd much rather have an FO beside me who's had a few frights and made a few decisions from the left seat of an ATR or a Dash 8 than someone who's gone straight onto jets and has only RHS time.
Such people may require a little more initial conversion training onto their first jet, but I think they'd handle the line flying as well as, if not better, than many currently coming into EK.
